The European project Green Hysland The project, in which the University of La Laguna participates, recently held its general assembly in Mallorca. The aim of this initiative is the deployment of a hydrogen ecosystem on the Balearic island. The project, which began in January 2021 and will run until December 2025, seeks to demonstrate the capacity of hydrogen to decarbonize EU islands and other territories, maximizing the integration of energy from renewable sources.
The University of La Laguna's participation focuses primarily on replicating the proposal in the Canary Islands, an activity that will occupy a large part of this research center's involvement in this final stage of the project. The principal investigator attended the assembly on behalf of the University of La Laguna. Ricardo Guerrero and two more researchers on the project, Elena Pastor y Juan Albino Méndez. During the working sessions, the status of all project packages and activities was updated, and visits were also made to the main facilities that make up the ecosystem being created.
The project will be implemented in Mallorca, where the aim is to establish an integrated ecosystem by deploying hydrogen throughout the entire value chain to demonstrate sectoral coupling. The project integrates various applications, considering different end uses of H2, such as its integration into the island's gas network, its use to fuel a fleet of hydrogen buses, and electricity generation at the Port of Mallorca, in hotels on the island, and in other municipal buildings.

The 100% green hydrogen production plant, managed by ENAGAS Renewable, is located on CEMEX land in Lloseta. From there, the hydrogen will be transported to its points of use via various routes. The H2 pipeline and the injection point for some of the hydrogen produced at the plant into the island's natural gas network will be operated by Redexis. Other companies and entities are also involved in the project.
The project, with a total cost of €21 million funded by the European Union's Clean H2 JU program, has seen €13.8 million invested through 2024. Regarding progress, the pre-commissioning of the electrolyzer (the equipment that generates hydrogen) has been completed, while acceptance testing (SAT) of the units is nearing completion and the generation and quality of the hydrogen produced is already being tested. In fact, the electrolyzer has been producing hydrogen since March 2024, and the tubular trailers are also currently undergoing testing.
The companies Redexis and Calvera, whose activities focus on the infrastructure for distributing green hydrogen to its final application, are conducting tests to verify the H2 piping systems, portable storage units, and transport trailers before final deployment. Regarding the applications, in the Balearic Islands Port Authority, the civil works for the generation plant and the acquisition of the fuel cell are underway. Meanwhile, for electricity generation in hotels, the permitting process for the installation is being completed, and tests are being carried out at the H2 plant. It was noted at the meeting that one of the outstanding issues is the final location of the hydrogen refueling station for the vehicle fleet, for which they are working jointly with the transport company EMT.
